Hi, hopefully someone can help... I have a Mac OSX version 10.5.8. Approx 9 months ago started having problems with it... Spinning ball, Safari not responding. The problem starts slowly but soon gets worse and worse... and eventually other programs are neither responding (as finder and preview), making it impossible to use the computer. Only option is to delete and re-install everything, then my mac works fine for approx 4 to 6 weeks until the same things happens AGAIN. Have deleted and reinstalled 5 times now!!!! Anyone has any idea what is causing this problem? Any suggestions? Done hardware search and nothing seems to be wrong, neither with the RAM. I have tried to use different browsers and same problem happens. Thankful for any help I can get!
